Vyew Rooms are continually auto-saved

Each meeting takes place inside a Vyew Room. A Vyew Room is a collection of pages which can hold many types of content which is available to the participants in that room. All content created and uploaded to Vyew is continually auto-saved and can be accessed anytime by any users to whom you allow access.

The Vyew Room also houses the communication tools listed below.

Communicating within Vyew

VoIP (Voice over IP) – Use your computer mic and headset to talk to people in your Vyew room.

Webcam – Up to 4 people at one time can broadcast their camera to everyone in your Vyew Room.

Text Chat – Chat with everyone in your Vyew Room, or initiate a private chat with one viewer.

I would like to share screens, however I have multiple screens. is there a way to change which monitor/screen is being shared? When I chose the crop option, Vyew only allows me to select an area on the primary screen.
